16.36.050 Administrative provisions.
A. The administrative portions of this chapter shall be overseen by the director of public works or his/her designee. The enforcement provisions of this chapter shall be overseen by the director of planning and development services pursuant to WCC 2.32.030, the director of the department of health pursuant to WCC Title 8, Health and Safety, and Title 24, Health Code, and the county sheriff, or their respective designees.
B. This chapter is adopted under the authority of the State of Washington Water Pollution Control Law, Chapter 90.48 RCW, and the Federal Water Pollution Control Act (also known as the Clean Water Act, Title 33 United States Code, Section 1251 et seq.).
C. Prohibited Discharges. No person or entity or others under their control shall throw, drain, or otherwise discharge a pollutant to the county’s MS4 and/or surface and ground waters.
D. Conditional Discharges. The following types of discharges shall not be considered illegal discharges if they meet the stated conditions, unless the director of public works or his/her designee determines that the type of discharge, whether singly or in combination with others, is causing or is likely to cause pollution of surface water or groundwater.
1. Discharges from Potable Water Sources, Including Water Line Flushing, Hyperchlorinated Water Line Flushing, Fire Hydrant System Flushing, and Pipeline Hydrostatic Test Water. Planned discharges shall be dechlorinated to a concentration of 0.1 part per million (ppm) or less, pH-adjusted if necessary, and volumetrically and velocity controlled to prevent resuspension of sediments in the MS4.
2. Discharges from Lawn Watering and Other Irrigation Runoff. These shall be minimized through, at a minimum, public education activities and water conservation efforts.
3. Dechlorinated Swimming Pool and Spa Discharges. The discharges shall be dechlorinated to a concentration of 0.1 ppm or less, pH-adjusted and re-oxygenated if necessary, and volumetrically and velocity controlled to prevent re-suspension of sediments in the MS4. Swimming pool cleaning wastewater and filter backwash shall not be discharged to the MS4.
4. Street and Sidewalk Wash Water, Water Used to Control Dust, and Routine External Building Wash Down That Does Not Use Detergents. The county will reduce these discharges through, at a minimum, public education activities (see Section S5.C.1 of the Western Washington Phase II Municipal Stormwater Permit) and/or water conservation efforts. To avoid washing pollutants into the MS4, contractors must minimize the amount of street wash and dust control water used. At active construction sites, street sweeping must be performed prior to washing the street.
5. Other Nonstormwater Discharges. The discharges shall be in compliance with the requirements of the stormwater pollution prevention plan reviewed by the county, which addresses control of construction site dewatering discharges.
E. Permissible discharges:
1. Diverted stream flows;
2. Rising ground waters;
3. Uncontaminated ground water infiltration (as defined at 40 Code of Federal Regulations 35.2005(20));
4. Uncontaminated pumped ground water;
5. Foundation and roof drains;
6. Air conditioning condensation;
7. Irrigation water from agricultural sources that is commingled with urban stormwater;
8. Springs;
9. Water from crawl space pumps;
10. Footing drains;
11. Flows from riparian habitats and wetlands;
12. Nonstormwater discharges covered by another NPDES permit;
13. Discharges from emergency fire fighting activities in accordance with authorized discharges (Section S2 of the Western Washington Phase II Municipal Stormwater Permit);
F. Prohibition of Illicit Connections. Any connection to the county’s MS4 that allows prohibited or not-approved conditional discharges is prohibited. This prohibition includes the following activities:
1. Construction, use, maintenance, or continued existence of illicit connections to the county’s MS4.
2. Without limitation, illicit connections made in the past, regardless of whether the connection was permissible under law or practices applicable or prevailing at the time of connection. (Ord. 2010-002 Exh. A; Ord. 2009-067 Exh. A § 3; Ord. 2009-057 Exh. A § 3. Formerly 16.36.030).
16.36.060 Penalties and enforcement.
A. Any person who violates any of the provisions of this chapter shall be guilty of a civil offense and may be fined a sum not to exceed $1,000 for each offense. After a notice of violation has been given, each day of site work in conjunction with the notice of violation shall constitute a separate offense.
B. The penalty provided in subsection A of this section shall be assessed and may be imposed by a notice in writing either by certified mail with return receipt requested or by personal service to the person incurring the same. The notice shall include the amount of the penalty imposed and shall describe the violation with reasonable particularity. In appropriate cases, corrective action shall be taken within a specific and reasonable time.
C. Within 30 calendar days after the notice is received, the person incurring the penalty may apply in writing to the county for remission or mitigation of such penalty. Upon receipt of the application, the county may remit or mitigate the penalty upon whatever terms the county in its discretion deems proper. The county’s final decision on mitigation or revision shall be reviewed by the hearing examiner if the aggrieved party files a written appeal therewith of said decision within 10 calendar days of its issuance.
D. If work activity has occurred on a site in violation of this chapter, prompt corrective action, restoration or mitigation of the site will be required when appropriate. If this provision is not complied with, the county may restore or mitigate the site and charge the responsible person for the full cost of such an activity. Additionally, any and all permits or approvals issued by the county may be denied for that site for a period of up to six years.
E. In the event any person violates any of the provisions of this chapter, the county may issue a correction notice to be delivered to the owner or operator, or to be conspicuously posted at the site. In a nonemergency situation, such notice may include notice of the intent to issue a stop work order no less than 10 calendar days following the receipt of the correction notice, and provide for an administrative predeprivation hearing within 10 calendar days of the notice. In an emergency situation where there is a significant threat to public safety or the environment, the county may issue a stop work order. The stop work order shall include, in writing, the right to request an administrative predeprivation hearing within 72 hours following receipt of the stop work order. Failure to comply with the order to stop work shall be a gross misdemeanor punishable upon conviction by a minimum fine of $500.00 up to a maximum fine of $1,000 or one year in jail, or both. Under no circumstance may the court defer or suspend any portion of the minimum $500.00 fine for any conviction under this section. Each day or part thereof of noncompliance with said order to stop work shall constitute a separate offense.
F. The county may suspend or revoke a permit if the applicant violates the conditions or limitations set forth in the permit or exceeds the scope of the work set forth in the permit.
G. The prosecuting attorney may enforce compliance with this chapter by such injunctive, declaratory or other actions as deemed necessary to ensure that violations are prevented, ceased, or abated.
H. Any person who, through an act of commission or omission, procures, aids or abets in the violation shall be considered to have committed a violation for the purposes of the civil penalty. (Ord. 2010-002 Exh. A; Ord. 2009-067 Exh. A § 4; Ord. 2009-057 Exh. A § 4. Formerly 16.36.040).
